TEMPERATURE REGULATOR.

Application filed october 25, 1919. serial No. essaie.

Another object is Vrtolprovide means fory regulating the ylevel of liquid carried in the radiator whereby the radiating surface of the fluid, Vaside from V.the liquid itself, may bevaried. Y

Anotherobject is to provide Yin a device ot the class described multiple `pipes of differing ,lengths andmeans whereby any one of .these pipes may be connected to a drain pipe at will.`

t/"ith these and incidental objects in View,

Vthe .invention consists otcertain novel teatures ofconstruction-and combination of parts, the essential elements .of which kare Ahereinafter described withre-erence tto the drawings which accompany and `torni a part otthis specification.

In the drawings, Figure 1 `is aside elevation ,of my improved device as connected to a radiator irof the commongtype; Figure 21s a longitudinal section of the deviceshown inFigu-re 1; 'Figure 3 is a section taken on the gline 3--3, Figure 2 .Figure ,4L is a sectionv taken on the line 4 4, YFigure25; FigureA 5 is a sectiontaken on the line 5-5, Figure2; Figure 6 is a longitudinal section of a modification of the .device shown in Figuresjl to 5 AiIlClU'SVG; Fgltll@ 7 S il SGCOIll-detaihof Vrthese multiple notches are `numbered and the a modification .of xthe means employedlr'- nunierals thereon correspond with the -inulrotating multiple lpipes .to align anyl one desired with the-drainpipe; and Figure is asection taken on the line 8 8, Figure 7.

As shown in Figures 1 and 2, theY device is connected to a radiator `or container 1 by "nipples 2, which engage by screw connection with the barrel 3 of the device.

v A central pipe 4, having a closure 5 near the center thereof, engages by screw connerction atv6 with a head 7, having packing rings 8 at the lower end thereof, and 4slidable in the tube --9 joined to the barrel 3. A

header 10 is positioned near the head 7 with packing means 11 .therebetween so the joint between thejhead 7 and header 10 will/be kept Huid tight. f

n The header is -eatherkeyed at 12 .to the barrel 3 to allow vertical movement-therein and to prevent rotative movement therein.

A head 13 with packing nut 14@ closes the top of the barrel 3, allowing both rotative and slidable movement `therein of lthe piped.

The lfshaped arm 15 has o ui'nalledtherein at 16 a shaft 17,'havinga thrust collar 17 thereon, the .shaft `engagingiby screw .connection with acaplS attached to the piped, so the rotation of the crank 19 pinned tothe shaft 17 will, raiseor lower thepipe 4 and with it head 7 and header 10 which kcarries multiple pipes 20 of .diering lengths.

A collar 21 surrounding the .pipe 4f .positions therebetween a `lingered .collar 22 which is rotative kon the ypipe 4.

A forked lever 23, `trunnioned .at 24.0n the collar 22 has a .lug'25 engageable with any one ,of the ,multiplev rnotches y26 on the collar 21 so that by lowering the lever 23 and engaging the lug withv one -of these Vnotches the collar 21 andi through .it :the pipe 4 .with its .multiple vpipes 20.may be rotated. Hence any one ot' the multiple pipes 2O may fbe brought inline with the aperture-27 leading throughthe passageway 28 and L 29 tothe drain pipe 30, `preferably leading tothe boiler. y

It is therefore evidenty that the radiator '1 may be supplied with water up to .the `level ot that .one .ofl the multiple pipes y20 in line with the aperture 27 and that the depth of thelwater Iin Vthe radiator may be `Varied by bringing one of-the multiple Ipipes 2O `of a different length inline with the Vaperture 27.

Looking at Figure -3, it will be seenthat tiple pipes and while the fingered collar 22 could `not be rotated past the rib 22 of ythe 4ing the numeral of the pipe ydesired and vthe` fingered collar is brought snugly against the rib 22 the desired pipe will be in line with aperture 27.

It is also evident that if the crank 19 is rotated the entire set of multiple pipes may be lifted through the desired distance, and hence if the total possible vertical lift is at least as great as the difference in length of the multiple pipes that the level of the liquid in the radiator may be maintained at any required height. l

As an alternate construction, l may fashion the top of the pipe a with a collar 81 Figure 7 and fasten to the extreme top thereof a cap 32 with a rotatably mounted collar 33 positioned between the collar 3i and. the cap 32. ln this case the lever 23 is hinged at 34 on the collar 33 and engages at 35 with the cap 32 so the pipe el may be rotated by turning the lever 23 in a horizontal plane in much the same way as the action of the lever 23 heretofore described.

The arm 15 has journalled therein the shaft 16 to which the crank 19 and also the collar 17 are pinned, and as this shaft engages by screw connection with the cap 32 the rotation of the crank will raise or lower the pipe 4, this pipe being shown in Figure 7 in its fully raised position.

Referring again to Figure 2, the pipe Al may be provided as at 36, with transverse apertures connecting with the central bore 37, leading to the passageway 28, thereby constituting the longest one of the multiple pipes, and it is evident that the longest of the multiple pipes could be always left in connection with the' drains so as to have a positive limit to the depth of the liquid in the radiator'.

lVhen, however, a large number ofrnultiple pipes 2() are used there will always be one of the pipes in line with the aperture 27 so this transverse outlet wouldnot be necessary.

ln Figure G is shown a modification primarily designed for wheat heaters, and on account of the nature of the heating means the device hangs from the heater rather than extends above, and for convenience the regulating means are positioned on the lower end of the device.

ln this modification the outlet drain pipe 30 connects directly into the flange pipe 38 fastened to the barrel 3', and the transverse aperture 36, if used, would lead to the annular space 39, to which the drain pipes 30 connect.

The lever 23 and crank 19 are the same as shown in Figure 2 but are positioned at the lower end of the device instead 'of the top thereof. and connections from the multiple pipes 20 to the aperture 27 would be the same as heretofore described with respect to multiple pipes 20 and aperture 27, the pipe a having the head7 thereon instead of this head being positioned below the pipe as shown in Figure 2.

lVhile l have described my invention and illustrated it in several particular designs, l do not wish it understood that I limit myself to these constructions, as it is evident that the application of the invention may be varied in many ways within the scope of the following claims.
